You may find that the Weber has to be adjusted to make the most of the change 
(or you may find that the Weber was set up assuming a header).  Chris King's 
advice to talk to Ted Schumacher first is sound particularly if you have a 
Weber.  He'll be able to advise you on the best combination of carb set-up, 
header and exhaust and save you a lot of experimentation.
